I've spent hours searching the Internet, this forum, called Samsung and still can't find a solution. I apologize if this has been answered before.

I just bought this Smart TV and was able to hook up using a wired connection whereupon it immediately uploaded the latest firmware. But it fails with the wireless connection. It sees my router and I enter the password. It tries but then fails and gives the message to turn the router off and on again or to check to see if I need a security key. Turning the router off and on didn't help and removing the security key didn't either. The security key is set to one capital letter and 9 numbers. I have two laptops at home that connect to the Internet through the router with no problem. The TV is currently 3 feet from the router.

The router is a Netgear WGT624 v3. I have downloaded the latest firmware. I have tried the following security settings: none, WEP, WPA-PSK [TKIP], WPA2-PSK [AES], WPA-PSK [TKIP] + WPA2-PSK [AES]. The channel is set to 11 (also tried 6). I tried the modes: b only, g only, g and b, Auto 108Mbps. (With Auto 108Mbps, the channel automatically set to 6)

I took the TV to work to access the wireless router there. At first it didn't work. Then I changed to access the IP address automatically and it did work fine. I brought the TV home and tried the same thing. It fails as before. Do I need to buy a new router?

Unable to connect to the wireless router. Try the following: - Check that the router is turned on, and if it is, try turning of and on again. - Check if you need to enter a security key to use the router.

(As stated in the earlier post, I did both of the above.)

On the link you sent, at the bottom of the page, it says, "Once you have determined where your connection is failing, click on the link below that matches your issue." But there are no links listed. (But my browsers says the page is "Done, but with errors on page".)

OK, so this tells me that the router isn't even getting connected at all to the router. I realize that's what you implied initially, but this cinches it. I assume it behaves like this even with encryption turned off, right? So let me ask you this: does your router have MAC address filtering enabled?

I have the similar problem with the similar TV, we have been using it from 2 years, all of a sudden it stopped connecting to the net. On your support link it's the fourth picture where the red X appears between the router & the globe- the internet service fails, could you please help me out, thanks.

By encryption, I assume you mean the security key. Yes, I removed it and it still fails. I am at not at home now so I can't confirm about the MAC address filtering state. But as I recall, I tried leaving the router open and also limiting it to certain devices. Limiting it to only the TV did not work.

I'm ready to give up and get a router that supports 8021.11n because this will only support b and g - not n.

Thanks for checking in. I read all of your earlier posts when trying to solve this. I only posted when I couldn't find an answer. Yes, this is the router. I did as you suggested and it still doesn't connect.

Does this TV support "g" mode? In the only other related post where someone solved this problem, it was done by replacing the router with one that supported "n" mode.

But at this age, it can be problematic and why when the office tech makes such a call will carry a spare router to test with. It really can torque folk that other things connect but as you see this more and more, some gear just doesn't work with newer devices.

Part of the troubleshooting is getting wired along with another router.

Hope you find out what it is. It could be the channel number but I read "The channel is set to 11 (also tried 6)." so that's not it. On the outside chance the router's radio has gone wonky, try 1 as well.

Be sure you test that feature before you go much further. We know the browser is limited and some sites block TVs and then the Flash is again limited. Some folk go through all this and only discover the limitations later. Get wired to see if this is worth fixing.

And you do need another WiFi connection to see if it's the router or the TV. It could be the TV but until that test is done, we're not sure.

I have been accessing the internet successfully with the TV via a long ethernet cable strung through the house. For testing, I moved the TV to the computer room to make sure the wireless signal was strong enough. The point of the wireless TV is that my wife doesn't want to watch movies on the computer. We have had four other laptops access the wireless router at different times successfully for at least a couple of years.

Unless anybody can think of anything else, I'll order a new router over the weekend and report next week.

The TV is just under 30 feet from the router but it is almost in direct line of sight from the router. It sees the router with 5 bars of reception. (The cable has to go over pathways, around furniture, door, etc.)

Plus to make it easier when I did the testing, I also brought the TV to the same desk as the router. They were about 4 feet apart.

I have a 46ES7000 model and just upgraded my wifi to Apple's latest Airport extreme. I now use my o2 router as a modem. However when I tried to change the network settings on the TV it searches for networks under menu > network > network settings and finds a list of servers including Airport Extreme for a split second and then crashes and you have to press the menu button and find network settings and repeat the process again and again. After about 3 attempts it can't find any servers.

As the tv is on the wall I don't particularly want to try and hardwire the router to the tv otherwise I'll have to get the deorators in!
